The specific works process of wheel rim crimping one-shot forming mould of the present utility model is as follows:
The first, as shown in Figure 1, shown in Figure 5, the semi-finished product wheel rim 11 after roll forming is placed on each counterdie shaping slide block.The Single port of semi-finished product wheel rim is enclosed within a counterdie shaping slide block.Each side lip block is positioned at outside semi-finished product wheel rim.
The second, cope match-plate pattern moves down, and in the process that cope match-plate pattern moves down, promotion translator slider and side lip block move toward semi-finished product wheel rim direction by the second Compress Spring, and four side lip block synchronizing movings, as shown in Figure 4; Until semi-finished product wheel rim is held tightly by four side lip blocks.After semi-finished product wheel rim is held tightly by four side lip blocks, this semi-finished product wheel rim is coaxial with counterdie guide pillar.
Then, cope match-plate pattern continues to move down, and when end in contact under the upper end and patrix fairlead of semi-finished product wheel rim, now semi-finished product wheel rim upper end-face edge will be positioned at annular crimping groove; After this, when cope match-plate pattern moves down, float support plate, radial passing enclasp device and semi-finished product wheel rim together will move down with cope match-plate pattern;
Again then, cope match-plate pattern continues to move down, and when the lower end of semi-finished product wheel rim contacts to set upper side with lower die guiding, now semi-finished product wheel rim lower edge will be positioned at lower annular flange groove; After this, in cope match-plate pattern folding process, the upper and lower end edge of semi-finished product wheel rim will complete the crimping process of wheel rim gradually in upper and lower annular flange groove, as shown in Figure 5;
When the lower end abutment of side lip block is on the upper surface of counterdie fairlead, and when the upper end of side lip block is resisted against on the lower surface of patrix fairlead, cope match-plate pattern stops moving down; Now, complete the crimping processing of wheel rim, form crimping 11a at the two ends up and down of wheel rim, as shown in Figure 5, Figure 6.
In addition, as shown in Figure 5, Figure 6, in cope match-plate pattern folding process, when behind the upper limit breach bottom surface and position-limiting drum upper-end contact of patrix shaping slide block.After this, in cope match-plate pattern folding process, counterdie shaping slide block is under the lower Rotary-table effect of counterdie guide pillar, and each counterdie shaping slide block will be expanded outward; Meanwhile, patrix shaping slide block is under the upper Rotary-table effect of patrix guide pillar, and each patrix shaping slide block will be expanded outward.When upper and lower mould shaping slide block will be expanded outward, upper and lower male cone (strobilus masculinus) will carry out shaping (forming the conical surface of inclination) to the bcad seats of wheel rim; Make wheel rim while crimping processing, the disposable shaping completing bcad seats, thus effectively reduce labour intensity, improve wheel rim production efficiency, shorten wheel rim fabrication cycle.
3rd, after semi-finished product wheel rim completes crimping and bcad seats shaping, cope match-plate pattern moves.
Cope match-plate pattern moves past in journey, float support plate, radial passing enclasp device and wheel rim under the first Compress Spring effect, will move first; When float support plate is resisted against on annular stop projection, float support plate moves on stopping, and now side lip block is positioned at the top of lower limit guide pin bushing; After this, on cope match-plate pattern continues in the process of moving, drives translator slider and side lip block toward moving away from wheel rim direction, thus are discharged wheel rim by stay cord.After cope match-plate pattern stops, wheel rim takes out by operator.
In addition, cope match-plate pattern moves past in journey: under the effect of second time Compress Spring and lower elasticity hold-fast ring, counterdie backing plate and counterdie shaping slide block reset; On second Compress Spring and on elasticity hold-fast ring effect under, upper die plate and patrix shaping slide block reset.
